Translation research - how to enter data into this program?

I'm conducting a research on Machine Translation and I need to run two programs that compare a text translated by a human translator with a text produced by a computer. The result of the comparison should be presented in the 0-1 scale e.g. 0.569165243. The problem is that I know nothing about programming I've downloaded the two scripts and opened them in Dev-C++ but I have no idea where and how to enter the paths of the files that need to be compared.
Could anyone please help me? Here are the scripts and their documentation (you need to delete the space after "http"):
